bashunixcommandtruncate

What is a unix command for deleting the first N characters of a line?

For example, I might want to:

tail -f logfile | grep org.springframework | <command to remove first N characters>

I was thinking that tr might have the ability to do this but I'm not sure.

Solution

  • Use cut. Eg. to strip the first 4 characters of each line (i.e. start on the 5th char):

    tail -f logfile | grep org.springframework | cut -c 5-
